4-Hydroxy-3-nitroso-naphthalene-1-sulfonic acid is a complex organic compound with the molecular formula C10H7NO5S. It is characterized by the presence of a naphthalene ring, which is a fused ring system consisting of two benzene rings. The compound features a hydroxyl group (-OH) at the 4-position, a nitroso group (-NO) at the 3-position, and a sulfonic acid group (-SO3H) at the 1-position. These functional groups confer unique chemical properties to the molecule, such as acidity and reactivity. The sulfonic acid group, in particular, imparts water solubility and makes the compound a strong acid. This chemical is not commonly found in household products but may be used in specialized industrial applications, such as in the synthesis of dyes or as an intermediate in organic chemistry. Due to its complex structure and potential reactivity, it is important to handle 4-hydroxy-3-nitroso-naphthalene-1-sulfonic acid with care, following appropriate safety protocols.

Check Digit Verification of cas no

The CAS Registry Mumber 7356-71-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,3,5 and 6 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 7356-71:
(6*7)+(5*3)+(4*5)+(3*6)+(2*7)+(1*1)=110
110 % 10 = 0
So 7356-71-0 is a valid CAS Registry Number.
